RE: Channel Spec

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you can find an AISC 5th Edition, you will note that the U designation was used with the first number indicating the depth in inches and the second number indicating the weight in pounds per foot.  I believe it is in part 1.  I don't have it in front of me.

It,s not a U. It's a [ (best I can do looks like a channel) That's how they used to designate channels.

It's a channel. "Purlin" just describes its function. If it's on the roof it's a "purlin". Same section on the wall would be a "girt".
